Title: Stirling cycle gas freezer
Inventor: KASHIWAMURA KAZUO
IPC: F25B9/14
Filed: 1994-07-01
Abstract: PURPOSE:To prevent wear of a piston and a cylinder at a gap seal part and wear of a cold finger and a displacer and leakage of gas by a method wherein one or both of the displacer and a piston are supported at a cold finger or a cylinder by a diaphragm. CONSTITUTION:One or both of a displacer 4 and a piston 2 are supported at a cold finger 3 or a cylinder 1 by a diaphragm 5 or 36. This constitution brings the displacer 4 and the cold finger 3 into non-contact with each other and prevents the occurrence of frictional wear therebetween and leakage of gas through a gap between an expansion space 6 and a first compression space 7. Similarly, since the piston 2 and the cylinder 1 are in a non-contact state, frictional wear therebetween is prevented from occurring and leakage of gas through a gap between a second compression space 8 and a buffer space 15 are prevented from occurring. This constitution prevents the occurrence of deterioration of cooling performance owing to leakage of gas.
